AUDIO PANEL AND CNS 4.5 ADDITIONAL AUDIO PANEL FUNCTIONS POWER-UP The Audio Panel performs a self-test during power-up. During the self-test all Audio Panel annunciator lights illuminate for approximately two seconds. Once the self-test is completed, most of the settings are restored to those in use before the unit was last turned off. MONO/STEREO HEADSETS Stereo headsets are optional for use in this aircraft. INTERCOM The GMA 350H includes a six-position intercom system (ICS), one MUSIC input, and one telephone/ entertainment input for the pilot, copilot and passengers. The intercom provides Pilot, Copilot, and Passenger audio isolation. Figure 4-40 Intercom Controls Press the PILOT, COPLT, and/or PASS Keys to distribute as required. If the annunciators are lit, those positions will share intercom audio. If an annunciator is NOT lit that position is isolated from the others. COPILOT CONFIGURED AS CREW OR PASSENGER NOTE: When the copilot position is configured as a passenger, the COPLT Key is disabled and the copilot headset is treated as a 'passenger' for intercom and entertainment audio distribution. The copilot position can be configured as crew (COPLT Key enabled) or as a passenger (COPLT Key disabled). Pressing and holding the COPLT Key toggles the copilot position configuration between passenger and crew. The aural message "Copilot Configured as Passenger" or "Copilot Configured as Crew" is heard. 190-01255-00 Rev. A Garmin G1000H™ Pilot's Guide for the Bell 407GX 123
